How is this different from other online PDF tools?

Most online PDF tools send your files to a remote server for processing. This tool processes everything locally in your browser using client-side JavaScript. Your files are never transmitted to any server, which means your document content stays entirely under your control.

Are my PDF files uploaded?

No. Your files are read directly by your browser. Your files are never transmitted over the network. The tool works entirely within the browser tab you have open.

Can I verify that files are not uploaded?

Yes. Open your browser's developer tools (F12), go to the Network tab, and watch for any outgoing requests while using the tool. You will see no file data leave your browser. The site may record an anonymous page-view count, which never includes your files and can be disabled.

Does this tool work offline?

Yes, once the page has loaded the tool processes your files entirely in your browser; tool functionality needs no network connection. You can disconnect from the internet and continue using it.

What happens when I refresh the page?

Because nothing is stored on a server, refreshing the page clears your current session. Any files you had selected will need to be selected again.

Does this tool store my files?

No. Files are held in browser memory only for as long as the page is open. Closing or refreshing the page discards them. Nothing is written to disk by the tool, and nothing is sent to a server.

Can this tool unlock password-protected PDFs?

No. This tool does not attempt to remove or bypass PDF password protection. If you know the password, the Unlock PDF tool on this site can remove it locally; then this tool can process the file.

What technologies does this tool use?

This tool uses client-side JavaScript and pdf-lib to copy consecutive page ranges into separate PDFs entirely within your browser — your files never leave your browser.

Does this tool use WebAssembly?

No. This tool uses client-side JavaScript and pdf-lib for local PDF structure editing. No WebAssembly is involved.

How do I split a PDF into fixed-size files?

Pick a PDF from your device, type how many pages each file should contain in the pages-per-file box, then choose Split. The tool builds the resulting set in your browser and gives you a separate download button for each part.

What happens to the leftover pages if the page count isn't an even multiple of N?

The tool walks the document in consecutive chunks, so the final file simply holds whatever pages remain. For a 10-page PDF split every 3 pages you get four files: pages 1-3, 4-6, 7-9, and a last file with just page 10.

What are the output files named?

Each part is saved as part-01.pdf, part-02.pdf, and so on, in page order. The number is zero-padded to match the total count of parts, so a large split sorts correctly in your file manager.

Does the Split PDF Every N Pages tool cost anything to use?

Splitting your PDF into fixed-size page chunks is completely free — no account, no sign-up, and no cap on how many documents you run through it, and it always will be. The entire process happens inside your browser using pdf-lib: your PDF is read into browser memory, divided into the page groups you choose, and each output file is handed back to you as a direct download — your document never leaves your device.
